Procedure

Thionyl chloride (8 mL) and N,N-dimethylformamide (few drops) are added to a solution of 3-(3-methoxy-phenyl)-pyridine-2-carboxylic acid (11.86 g) in dichloromethane (80 mL). The mixture is heated to 40° C. and stirred at this temperature overnight. The solution is then concentrated and the residue is taken up in toluene and concentrated again to give the crude title compound that is used without further purification in the next step. Yield: 12.80 g (crude).
